RADIATOR WITH"REMOVABLE EIJEMENTS.

Application filed November 22 1922. Serial No. 602,582.

To all whom it may concern:

Be it known that I, HENRI RAYMQND" GUYor, a citizen of France, residing at 54 Avenue Jean Jaures, in the city of Paris, France, have invented an Improved Radia tor with Removable Elements, of which'the following is a full, clear, and exact de-' scription.

This invention relates to a radiator for motor cars and other vehicles comprising removable elementsor parts held Within a frame so as to allow them to berep'laced or isolated from the others in case ofaccident.

The elements of this radiatorare provided upon an upper collectorand a lower collector, with a joining device comprising a shell or box secured to a fixed plugpro vided with ports. When the radiator is operating normally, this joining device is ample, but when the element is'to be isolated or separated, a shutter or closer is added to this device. The device thus combined forms the characteristic feature of the invention.

This invention will be hereinafter described by way of example with reference to the accompanying drawings-in which:

Figure 1 shows in front View, part of. a radiator with removable elements made according to this invention,

Figure? is a vertical cross section made through one of the removable elements,

Figure 3 is a vertical cross section of a connection without the closing device.

Figure 4 shows in vertical section one form of shutting or closing. device as applied to the connection.

Figure 5 is a modified form of the: shutting or closing device shown in Figure 4.

Figures 6 and 7 show other modified forms of this closing device.

Figure 8 shows in section adevice provided with an insulating partition arranged inside the connection.-

Figure 9 shows a closing'shell ready to split the insulating partition.

Figure 10 shows the shell in'position after the partition has been pierced.

Figure-11 shows in longitudinal section a modified form of closing shell made of two parts.

Figure 12 shows the point or tip of the shell engaged in the connection.

hFigure 13 shows in section the body of the s ell.

As shown in Figures 1 and 2 of these drawings, this radiator comprises removable elements A which can be of any system. This radiator comprises an upper header B and'a lower header B upon which are u secured joining devices which-allow the elementsA to bereplaced or isolated.

The joining devices are secured to the chambers a of the'elements A, Figure 3, and each comprises a sleeve I), placed upon a hollow connection 0 opening into the head ers B and B of the radiator and. secured to the headers.

When the elements are brought into position by causing them to move in the direction of the arrow, Figure 3, the cap d is screwed tightly until the two soft gaskets e are. compressed.

The radiator header is directly connected with the chamber of the element through the holes or ports 7 of the connection 0 and the sleeve 1), so that, during the normal running, the liquid to be cooled circulates without obstruction.

When it is intended to then isolate the element, it is only necessary to unscrew the cap 03 and to introduce into the hollow connectionc a shellg, as shown in Figure 4.

The closing. shell 9 is composed of two cylindrical pistons entering one another 9 and 9 within which a coil spring 72, is en closed;

The external piston g is provided with a rest or shoulder g for a gasket 71, but this pistonmay be of any other form.

The screwing of the cap (Z causes, through the piston g and the spring h, the piston g to press the gasket i against the shoulder c of theconnection 0 thus producing a comp'lete closure.

Inaorder to re-establish the circulation in the' element, it is only necessary to unscrew the cap'd,-to'remove'the whole of theshell g, and. place the cap again in position.

In Figure 5, the shell in'question is formed of a single sliding piston g held by a spring 72; pressing against a washer j mounted upon ing an elastic pressure and a complete clo sure.

In Figure 6, the shell is composed of a stopper made of india-rubber or any other extensible substance 9 through which passes a screw-stem or bolt m provided, at one end, with a head m and at the other end with any suitable nut m I'Vhen tightening this nut, a pressure is exerted upon the two ends of the stopper which swells and then shuts off the port or holes 7. I

Figure 7 of the drawings shows a modified form in which the shell 9 is pressed against a gasket 2' by means of a screw it screwed into the'hollow connection 0.

I In the modified form shown in Figures 8 to 10, the inner portion of the connection a is provided with a shoulder 0 near the inlet portion upon which is applied a thin insulating partition as which can be of any suitable material provided it can be easily pierced. I

In case such a partition is used, the'shell g is provided with a point 9 adapted to pierce this partition. The perforated partition then surrounds the body of the shell as shown in Figure 10 of the drawings, after the screw-plug 3 has driven this shell home so that its soft fittingz'presses against the obturating cone 0 The use of this partition avoids waste of water when an'elemen't is being isolated. I

In the modified form shown in Figures 11, 12 and 18, the shell is made of two parts, so that its head only may be used when it is desired to replace a damaged element by a spare one without emptying the radiator. To this purpose, the body of the shell and the point or tip thereof are made removable so as to allow a quick separation of these two parts. 7

In this case, the body 9 ofthe shell, is provided at the front, in order that it can be separated from its point or tip 9 with a threaded cylindrical part g forming a. stud which is screwed into a tapped part 9 in the back of the shell point. r

This conical point is provided with a shoulder g and a. central; threaded stem 9 A soft washer i made of india-rubber for instance is placed upon the part 9 and rests upon the shoulder 9 it is pressed by a metallie washer 9 and a nut g against the shoulder g so as to produce its expansion.

The nut g has a conical point 9 which acts as a punch in order to pierce the insulating partition to, as above stated. r

The insulation of. a damaged element is performed quite simply in the following manner: 1st. The cap is unscrewed; 2nd. The insulating partition is pierced by means of the point 9, which. prevents the water of the radiator from flowing out; 3rd. The closing shell is pushed home until its soft part 2' comes in contact with the cone 0-".

After the cap (Z has been again screwed so as to cause the shell to firmly bear against the cone 0 the radiator may then be operated again. i 4

If during the journey, it is desired to replace a damaged element by a spare one, without emptying the radiator, it is only necessary after having effected the insulation, as above indicated, to unscrew the tightening nut (Z which enables the substitution of an element for another without any waste of water.

The newelement being kept in position bythe nut al it is then put again in circuit with the collectors of the radiator by withdrawing the shell until the soft part of the head comes in contact with the inlet part of the connection 0, then the body of the shell is separated from the head.

Finally, after the cap d has been placed again in position, the radiator is ready to operate with all its elements.

The head of the shell which closes the connection 0 can be removed and replaced by a spareinsulating partition w.

The forms, details, accessories, materials and sizes of this radiator can of course vary withoutin any way departing from the principle of this invention.

What I claim is 1. In a radiator having removable elements, a tubular member connecting the header of the radiator with an element thereof, a cylindrical member adapted to be inserted in the'tubular member for closing the communication between a header and an element, said cylindrical member comprising two telescoping and spring-pressed sections, and means for telescoping the said sections.

2. In a radiator having removable elements, a tubular member connecting an element with a header of the radiator, a member adapted to beinserted in the tubular member for closing the communication between the element and header, said closure member comprising two cylindrical shells each having a closed end and telescoping one in the other, and a spring in the shells and engaging the closed ends thereof, and means for telescoping the said shells.

3. In a radiator having removableelements, a tubular member connecting an element ofthe radiator with a header thereof, a breakable partition at one end of the member, a cylindrical member adapted to be inserted in thetubular memberfor clos- I and header, said cylindrical member having a pointed end, whereby the partition will be broken and caused to surround said member as it is inserted in the tubular member.

l. In a radiator having removable elements, a tubular member for connecting an element of the radiator with a header thereof, a member adapted to be inserted in the tubular member for closing the communication between the header and an element, said closure'member comprising two telescoping and spring-pressed shells having a removable head provided with a gasket surrounding the same, and means for telescoping said shells.

5. In a radiator having removable elements, a tubular member for connecting an element of the radiator with the header thereof, said member having a beveled surface at one end and provided at its other end with a breakable partition a member adapted to be inserted in the tubular menu-- HENRI RAYMOND GUYOT.
